• Promotes Relaxation (Calm without Drowsiness) — L-theanine increased alpha brain-wave activity associated with relaxed alertness.
(NIH/PubMed — Nobre AC, 2008)

(NIH/PubMed — Kimura K, 2011)

• Supports Attention & Mental Performance — L-theanine (often in combination with caffeine) improved attention and task performance; synergistic effects noted with caffeine co-administration.
(NIH/PubMed — Owen GN, 2008)

• Supports Mood & Emotional Well-Being — L-theanine supplementation improved anxiety and depressive symptom scores in healthy adults.
(NIH/PubMed — Hidese S, 2017)

• May Improve Sleep Quality* — Trials report sleep benefits in select groups (e.g., pediatric ADHD; adults with stress), though findings are population-specific.
(NIH/PubMed — Lyon MR, 2011)

(NIH/PubMed — Rogers PJ, 2008)

(NIH/PubMed — Nobre AC, 2008)
